The Results: Big Influencers

Why Micro Influencers Performed Better
There are several reasons why micro influencers provided a better CPA:
- Their followers are mainly all beauty-related. When scaling up to more prominent influencers, people follow them for various reasons, not just beauty content.
- Micro influencers don’t get hit up to promote products and services as much, so they’re more flexible and open to partnerships.
- They try harder to please brands to secure repeat business, leading to more genuine and engaging content.
In conclusion, while micro influencers typically provide a better CPA, it requires more work to manage them as you need a large number of them to make a significant impact. The choice between micro influencers and well-known influencers ultimately depends on your brand’s goals, resources, and target audience.
